CASE. B.

To all whom it may concern:

Be it known that I, LOUIS GODDU, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful I mprovemen ts in Screw-InsertingMachines for Fastening the Soles of Boots and Shoes; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to which it pertains to make and use the same,

reference being had to the accompanying'drawing, and to the letters of reference marked thereon, which form a part of this specification.

Machines have heretofore been constructed to insert screws to unite the uppers to the soles of boots and shoes by severing such screws from a threaded coil of wire. In such machines the threaded wire has been seized and inserted by a clamping device, which is then released to make the succeeding clamp and feed, and insert the next screw. In such intermittent seizing and clamping device the crushing of the threads of the screw is unavoidable.

. It is of great importance, and absolutely necessary, that the threads of the screw be kept from being crushed by the action of the clamping device in seizing the wire; otherwise the holding powerofthe screws would be greatly diminished and rendered uncertain. It is one of the distinguishing aims of my invention to remedy this serious defect, and to produce such a machine in which the work may be rapidly and perfectly done. i

In the organization of my new screw-machine I have combined a head carrying the feeding and griping devices for the wire, and having a compound automatic vertical and laterally reciprocating movement, one of such movements beingto adjust itself to different and varying thicknesses of work, and the other to effect the feed of the .head over the work. With this last orside reciprocating movement of the head the work-support co-operates .and .The screw is inserted while these parts are moving to the left, and the return movements of the head .and. the

work-support determines the feed by the extent of such movement, the work remaining in its position against an edge-guide, and both the head and the work-support take their positions at another point with respect to the work ready to insert the succeeding screw. The support for the work, which in the example shown is a rotatable horn, is mounted'by means of an arm upon the stein, which carries and gives the head its compound motion, while the horn-axis has a bearing upon the standard. I

The wire-carrying spindle is of novel construction, having a nose projecting between slides which hold the wire-severing knives, and the feed of the wire is elfected by a sliding segment of the spindle, having a revolving motion with the spindle, and an automatically varying vertical movement independently of such revolving motion, to alter the length of feed to correspond tot-he thickness of the-stock to be united. of the spindle is not only new, but the means for producing the result stated are also new,

and consist in combining with such segmentslide a stop acting on a fixed point in the standard. The head is held from having-any vertical movement while the screw is being inserted by means of an automatic locking device, the peculiar construction and operation of which allows it to be used as the means whereby the head is raised as soon as the.

a front elevation of the same ;'Fig. 3, an elevation of the left side ofthe same. In these three views the headis shown in its normal position upon the standard. Fig. 4, a vertical This construction section of the spindle, showing thefeeding and holding devlces enlarged; Fig. 5, an ele- Fig. 12, an elevation of the head, showing its relation, when raised, to the standard, the adjustable edge-guide, and the horn; Figs. 13, 14, and 15, details of the pivoted armed spool for the coil of wire; and Fig. 16, a sectional view, showing the adjustable ed ge-guide.

The work-snpportA is mounted upon the stem B,.Fig. 1, which also carries the head ofthe machine, and these two elements are mounted upon a standard, G. The spindle D,

1 through which the wire a passes, is arranged in linewith the axis of the noseof the worksupport. It revolves in' vertical bearings D of the head E, and: carries at its upper end the spool F for the coil of wire, and inposition to allowiit to uncoil in line with the wire pas sage in the spindle. It is revolved by a pulley, F, at its upper end, andhas a worm-gear, G, whichimparts motion to the cam-shaft through a geaawheel, G thereon.

. The feed-rollsH are .situated within an enlargement,I, of the lower end of the spindle, and the. device by which they are operated greatestdiameter of the spindle,and the. up-

..1 per partot this segment has a screw-thread, b,.on itscircumference, to receive a threaded sleeve, 0, upon which a loose collar, 0, is secured by a nut, Figs. Land 5. This collar. 0

has vertical. movement upon the spindle,

andwlthe slide-segment J moves with it, hecause its screwthreaded portion b is of a greater diameter at that point than the spindlepand. thus. all friction on the spindle is. avoided and a free vertical movement given toithe slide-segment. The lower part of. this segment J is provided with cogs d, Fig. 4, having agroove c, Fig. 4:, at right angles with i the cogs, through which the .wire. passesto the griping. and feeding rolls H, and is there tbreinlinewith the wire passage of the spindle. 5; The feed-rolls areoperated by this rack; d bymeaus of a gear, f, havinga groove equal to halt the diameter of the wire,and which forms, with the groovee inthe slide-segment J, acontinuation of the wire passage of the spindle, and thereby forming aisupport for thewirewhile it enters thefeed-rolls immedi- The feed-rolls are of peculiar n i one of which I prefer to construct with an. an

nular concave screw-worm, k, Fig. 9, to suit:

ately below. In. its: upward. movementthe slide-segment J moves withoutoperatingthe feed-rolls, because the groovedgearf is mounted by a sleeve, g, Figs. 4 and 12, uponithe shaft, which carries at one end a ratchetwheel, 71., into which a pawl, @acts, fastened to the arm j of the gearrsleeve g, and at the: other end said shaft carries apiniomj", which, by an intermediate pinion, gears with a pinion, j, on the endof the feed-roll shaft. The other feedroll is made adjustable to givemore or less pressure upon the wire, and is heldiu a bearingplate, H screwed to the head of;

the spindle. Now, the operation of this wire feedingmechanismis as follows, viz: The wire being fed between the griping and feed rolls H, is held firmly and caused to revolve with the spindle, the slide'segment J being in its lowest position, andthe pawl 11 preventing the rolls from having anybackward movement at the time of severing the screw. The slide-segment J, in rising to take a new feed, being connected with the sleeved gear f, causes the sleeve-army audits ratchet-pawl to move backward, without turning the ratchet-wheelh. This givesthe pawl a new bite on the ratchetih,gwhen the segment to the feed-rolls, will turnthem, thus feeding down the wire.

the pitch andsize of thescrew-thread, and in which the thread embeds itself, so that;the pressure needed to. hold the. wire 1 can be ap-f i plied by the;opposite feed-roll; without injure ing the thread of thewire, while ithe other roll,

in order to give it theYmostperfect holding power, has two annular threaded ledges, Z, with i an annular groove between; them. 3 This double screw-wormfis of these-me pitchasf i. that of the other roll, and projects slightly bei yond the circumference of the roll, toalljowf them to enter between thejthreads and press I against the body or core ofsthe: wire at two or n n more separate and distinct points of. the cir-;i

I cumference of thebody of thewire. a This is n a most important feature, asit gives the; re

quired holding power upon the screw without 1 increasing the pressure to such an extent as; i would render thefeedin g difiicult. This hpldf -ing principle gives an intermittentxcontact, andallows the freepassageof. wirebetweeu fthemin the direction of its length, holding it firmly, to cause it torevolvewith the spindle, and preserving thethread ,rmm mplemen jury. The feed of the wire jbeing efl'ectediby the vertical unovements of the slid'e segment, I obtain this movement by means of 1 a lever, vK, having three arms, Fignlpand pivotedhto the head, one arm, k, of which is forked, land;

In this way the slide-segmeu t jlnoves up freely over the. wire and down, carrying the wire with it. y i 1 construction,

' Figs. 4. and 5, of the slide-segment.

connected by a pivoted block working in the fork to a vertical bar, m, moving in ways, and which is connected to the loose collar 0, Another arm, k is connected by pin and roll with the cam L, which gives it its motion, while the third arm 70 is connected to a vertical rod, a, passing through a base of the head, and which touches and rests upon an adjustable stop, 0,

Fig. 1, inside the hollow stem B which carriesthe head, each time the length of the feed is determined. This central gage-stop o is made adjustable by having a screw on its lower end.

passing through a nut in tile standard, and provided with a check-nut, o

The cam L, Fig. 12, which operates to depress the slide-segment being aface-cam, if the roll was always allowed to follow the surface of the cam d nrin g its revolutions it would raise the slide-segment always to its highest point, and consequently making the same feed. But if held from following the greatest curve described by the path of the cam L during any portion of its revolution, it is plain that the slide-segment J would not rise so great a distance over the wire, and consequently would not feed down so much wire. The higher, there. fore, the slide-segment is raised the longer will be the screw, and vice versa.

By this construction and combination the operating-cam L is made to perform the function of a series of cams, whichwould otherwise be required to give. the desired elevation to the slide-segment. This is accomplished in the following manner: When the .cam L has reached its greatest point of projection it will be seen that unless some pressure is applied upon the third arm k the second arm k would not follow the receding curve of the cam, so

a spiral spring, 19, Fig. 1, is arranged to press upon that arm is to throw it down. Now, if

the vertical rod a, leading from the third arm it, strikes the stop 0 in the base previous to the maximum throw of the cam being reached, it is plain that that will determine the height which the arm operating the slide-segment can raise just as differently as if the arm k had followed and rested upon the face of the cam during its entire revolution; Not only does this spring 10 and stop-rod a determine the length of feed for a particular or given thickness of work, but the operation is automatic.

The pressure-spring p is held in position by a rod rising from the third arm 70, and passmains stationary, it follows that the higher the head of the machine is raised the farther the vertical rod nwill descend before it touches the stop. Now, if I start with material which requires the head to be raised, say threeeighths of an inch, to place it upon the worksupport, the distance between the gage-stop'o and the end of the vertical rod 11. will be proportionately increased, and the moment the time comes for determining the length of feed at that point the cam-face Lrecedessuddenly and allows the compressed spring 1) to force down the vertical rod 10. through the space made by raising the head above the fixed gagestop 0, which it strikes, and thereby stops the further ascent of the slide-segment, and thus determines the length of wire feed down, which will correspond with the thickness of the stock.

Any point of elevation of the head caused by the thickness of the stock between its contact with the cutter-arms and the work-support will be in like manner determined.

It at any time it is desired to let themachine run and suspend the actionof the wire-- feeding mechanism, this'maybe effected by a set-screw, r, Fig. 1, passing through the base of the head in position to be forced against the vertical rod n, which acts upon the fixed stop 0 when said rod is atitshighest elevation,

and keep it from descending,.and-consequently holding the arm k from receiving any movtion fromthe cam L .until the rod n is unclamped. This gives very greatcontrol over the working of the machine without disturbing its other movements.

The screw having been inserted it is neces: s'ary to severit from the wire .veryqnick, and

just previous to the headbeing automatically raised.

The'wire-severing cutters sare-secu'red each T .to an arm, t, Fig. 8, which is fitted to slide within a groove formed in the under side of the head, and which arms t rest upon thework. One is longer than the other, and they areparallel to each other, and-provided with cogs t on their inner edges at the rear ends, into which a geared pinion, a, meshes for imparting opposite sliding movements to these arms, vthe longest one of which extends in front ofa vertical line through the spindle, and the shortest one terminates just back of said line,

gles, instead of in the same plane or at right angles to the length of the wire. This oblique set is made bybeveling the top and under surfaces of the cutters, so that their edges, when brought together, will form an X, as at X,

Sheet 3.

The advantages of this are, thatt-hejknives to enter more easily, and the end to rivet on the horn, making a more secure fastening, besidesleaving the inside of'the shoe perfectly smooth, as shown at X, Sheet3.

The cutters are h id in these arms flush with their ,under surfaces by set-screws,-so as to be adjusted in line with the axis of the spindle; and the arms are held in place 1 by, a bottom plate, t which also furnishes a hearing for the geared pinion a for operating the slides. A recess ismade in the upper surface of the arms t to receive a cylindrical projection which forms the nose D Figs. 4 and 5, of the spindle D, and by which the wire is supported as near as possible to the'stock to prevent it frombending under the pressure necessary to insert the screw, and bringing the end of the nose D the stock, and the cutters nearly in the same horizontal plane, and

cutting the wire level with the surfaoeof the stock.

The geared pinion for the cutter-arms is enlarged at its upper end to form a second pinion, M, Fig. 8, and has a bearing in the head. In this second pinion meshes the cogged endot' a lever, M, Fig. 1, pivoted in the head, andwhose upper end is acted upon by a small projection, to, on the circumference of thecamn L, Fig. 17, which operates the wire-feeding device. The vibration of the upper end of the lever M causes its lower cogged end to traverse back and forth over the pinion a turning the latter in alternate opposite directions,

and thereby give the same movement to the cutter-arms.

R It is necessary that the cutting of the wire be done instantly, and for this purpose the projection w is made very steep, and terminates abruptly, so that the cutters may at once opento allow the wire to again pass between them and enter the stock. i

. gTo open the cutters instantly after the severing of the wire, a spring, 00, Fig. 3, bears uponythe geared end of the pivoted lever M, so

as to throw it back, and thus cause the pinion a to revolve backward to open thecutters and bring the othc'rend of the lever in position to receive the action of the projection 10.

3 I have described the vertical movement of the head, and have stated thatin conjunction therewith it has a laterallyfireciprocating movement. To obtain this latter movement thei head is hinged at its rear by a vertical rod, N, Fig. 11, to a hollow post, N provided with an arm at each end, at rightangles to each other. post and enters a bearing in the head at each end, so that the. post rises and falls with the head, and the reciprocating lateral movement is made upon its central supporting-sleeve B.

r The post N has an oscillating movement, caused bycits upper arm N having a pin and roll connection with a groove-cam, 0, on the cam-sh aft,

while thelower arm N, Fig. 11, is forked, and

has an adjustable fulcrum-block working in a slot in the top of the rear of the standard;

This rodNpasses through the Any vibration ottheuppemrm N caused by its cam 0 necessarily causes the slotted arm N to vibrate in the samedireotion but this arm, being held byits fulcrum-block from any vibration, it musttlierefbreturn upon said fulcrum-block as a hinge; but the lower arm N being shorter than dthe other,causes the head to turn on its post-pin N and allow of:

the vibration of the cam-armN by the hingejoint connection of theheadwith thepost. 1 A variablelaterah movement of theheajdisef fected by moving the fulcrum-blockfof the lower arm N nearerto or farther fromlthe post-pinNJnorder thereby toVarythemOVe-I 1ment of the head over the work to increase or,

diminish the distance between the screws. 5

The adjustable fulcrum-block is of sufllcientf length to allow it to performits function at any elevation .of the head above the=horn.

The post-cam Ouis of such formas to cause a slow lateral movement of the head io take place to the left, and \vhilethe screw is being inserted, and a quicker movement in an oppo site direction, to placethe head in p sition over thehorn, to insert the next screw. A new element in the work-support consists inits having a laterally-reciprocating move-f ment with the head, and is: carried by the hollowsleeveB, upon which the head is mounted,

by means of a forked arm, P, extending from the sleeve, to which it is properly secured, and passes through an opening,.y, Fig. 1, in the standard; Thisforked arm? rests and moves upon a base-stud,z, which givesasupp0rtt'or its horizontal movement; and a pin, Qypassing vertically through theforked ends ofthis arm, forms the'support for the work-support. Upon this pin Qthe hornis mounted by a sleeve between thetbrkslof the armfso that it is free to have arotating movement,while the arm P. is allowed tozhave a verticalmovement with the head, without imparting. any

vertical movement to the work-supporhasthe f 1 play between the ends: of; the sleeve andfthe forkedarmsis equal to the greatest vertical :1

jplay of the head. .Thronghthe sleeve of the ;born is a set-screw by whichto fastenit to 0 the pin Q atjustthe propergheight. In machines in whicharotating horn hasbeen used,u

it has always been turnedupon afixedieenter;

1but in my plan the centeri upon whichthe Ihorn revolves is constantly changing initrave ersing an are over the base-stud, yet jalways maintaining its work-supporting end in=line with the spindle. By this constructionit work-support alsohas a ,compoundlnovement.

to carry itback and are; sidewise,:lto (le termine the distance between the screws, and ,pert'ect freedom to beturned on its axis; at the same time. The head is raised, asin FigrlZ,

to put the workhponthe} support, by means .of a treadle, R, pivoted tothe standard; 0, and.

having a vertical. rod, S, passing up through. the base of the standard andbearing upon the forked arm. P, whereit is connectedlwiththe willbe seen they sleeve B, supporting the head. In releasing the tread-1e R, thehead E automaticallyadapts itself to the varyin g thicknesses of the work. It is necessary to prevent any vertical move-. ment of the head during the operation-of inserting and cutting off the screw, and for this purpose I have devised an automatic locking device, constructed and operated as follows, viz: A pin, T, Fig. 10, rises from a projection on the standard and is provided-with a clamping device consisting of two blocks, 2 pivoted in a carrier, T, which moves up and down over the pin. The bearing-surfaces of these blocks 2 conform tothe shape of the pin T, and are pivoted in the same horizontal line, so that when the carrier T is kept horizontal these blocks 2 will move easily vertt cally over the pin. The inner end of this carrier T is fitted to move in a slot in the standard, and by which it is'held from moving sidewise. This carrier T is supported at its inner end by a rod, T the upper end of which is connected to the'base of the head, while the lower end passes some distance through. the carrier and has a spiral'spring, 02 upon which the inner end of the carrier rests with a nut resting upon the carrier so as to keepit level when the head descends. The outer end of the carrier is attached by a ball-and-socket joint to one end of a vertical rod, U, having a screw-extension, its other endbein g connected by a similar joint to the slotted end of an arm, V, pivoted 'to the-head, with a branch, V connecting it with a groove'ocam, V Now, so long as the carrier Tis kept in a horizontal position no clam pin g-pressure of the blocks 2 is applied upon the pin T; but so soonas one endis lowered the carrier becomes oblique to the positions of the blocks, and hence the blocks will be caused to bear by reason of their pivots upon the opposite sides of the pin T, and it is plain that any lifting .upon the raised end of the carrier must tend to clamp the pin more firmly. J ustprevious to the screw touching the stock, the cam V hasraised the vertical rod U, and with it the outer end of the carrier T thus clamping the pin. The rod U which has tilted the carrier being connected to the head, any receding of the head from the work would carry the rod U also higher, but which is prevented from so moving by reason of the carrier refusing to slide over the pin T, so that the greater force exerted to raise the head the more firm will be the grasp of the clamping device, thus making the head as rigid as if it had no vertical movement during the operation of inserting the. screw.

In order to get the head back over the work, to insert another screw, it mustbe raisedfrom the stock, and consequently the lock must be taken 0d; and this is done by the cam V forcing down the connectingrrod U, and depressing the outer end of the carrier T and applying-the lock in the opposite direction but this does not raise the head; but the rod U being prevented fromany greater descent by ingthe lock. This provision is made by the rod T connecting the head E with the inner end of the carrier T FigJlO, which, at this moment, is the highest, and the elevation'ot' the head carries up this rod with it by com-- pressing the spiral spring 00 which bears against the lower side of the inner end of the carrier, and this elevation of the head, is preserved du'ring part of its movement to the right over the work, when the cam V 'again allows the head to drop down suddenly upon the work and compress the parts tightly to.- gether, the clamp having been relieved from the pin T just previously to automatically determining the feed of the wire, and locking the head to insert another screw;

In uniting very thick work an auxiliary pressure of the head uponthe work isobtained by a rod, W, united to the head, and passing through'the arm of the standard with a spiral spring, w Fig. 3, exerting a constant downward't'orce upon the head, and which may be relieved when desired.

The locking device is automatic as regards time, and also works irrespective of the relative height of the head above the horn, and holds the head equally 'for all thicknesses of work.

The height to whichv the head. may be raised is regulated by adjusting the ball-aml-soeket connection in the slot 2, Fig. 10, of thepivoted arm V, nearer to or farther from the head E, to -suit the thickness of the work to be screwed together. This is important, because more elevation is needed when there is considerable difference in the thickness of the samesole, than with a sole of comparative uniform thickness.

Hitherto the work has been. moved over the horn in being fed, but in this machine the work is held stationary while the support and the head move over the work, bringing them in a new position on' the sole. In this plan the work is held by a selt'eadj usting'edge-guide, 12, Fig. 16, fitted in a bracketm and extending beneath the cutter-arms t. The point which acts on the edge of the sole is roughened to hold the shoe, with slight pressure,.t'rom moving back with the head when taking a new feed. Its seizing end is kept up close to the arms which carry the cutters by a spring, 41 actingv on its'under side, so that it will always strike the edge of the sole at whatever height the head may be.

It isadjustable lengthwise by cogged connection with a hand-lever,'u ,so as todetermine the distance of the screws from the edge of sole.

To control the speedofthe machine I em-.
